This invention relates'to improvernents indevices for cooling, washingand dehydrating air, and its leading-object is tojprovide a simpleand,

portable device for conditioning the, air-of a ;room so as to lower'itshumidity and at the.

same time, lower its temperature andxremove free dust from it. i- VAnother object of the invention is the provision of a. portable device,wherein the air is caused to circulate around a cooling surface,

which may be maintained at a. low temperature by means of a block ofice, or by means of any suitable motorized refrigerating means, and isthen directed through the upper layer .of a body 15, v of water in finestreams so as to produce a flow of air bubbles through or against theWater, so that heat is'surrendered to the water, free dust is taken upby the water, and the moisture of the water, by means of a distributingplate.

2 which is. formed with'numerous bubble directing channels, so arrangedthat't-he airflowjs directed toward the center of the device,"so as"tom'aintain considerable travel for the air 'bub bles and to'maintainthe same separate in dif-I so ferent paths, whereby the maximumfrictional' areaof the air quantities is presented to the water. i p IWiththe above and other objects in View the invention consists incertain new' and useful 35.,constructions, combinations, f andarrangement "ref-parts, clearly described in the followingspecification, and fully, illustrated infthe' accomQ provided withacentral 'airjop'ening 22.

Within the vessel or tank 5 an inner vesselor tank 9 is arranged, fisoas. to be .concentrically spacedfromthe wall of thevessel .5. This innervessel .or tankis supportedby. the cross bars, l0- above the'bottom'wallTfi ofthe outer vessel or l0 tank. "if

A force fan l fisfpositionled under the bottom wall of the inner vesselor tank and above the bottomwall of the outer vessel or tank, on theshaft l2 of the vertical motor l3, which is supported in place by thespider, which. comprises sections 1M and lithe radiating arms of which iare bolted "or 'otherwise' supported 'on the supporting legs 15L'I'hefspider. sections [4 and I5 are clamped tightly, around the bodyorfield of '20 theelctrioal motor1l'3 by means of the clamping,

"'I'he a'nnular wall of the inner vessel extends upwardly-under theannular member 8, so as to providejan air passage IBabovethe upper edge25 of the Wall of said inner vessel." The depending inner wall 80, of'said' annular member, which is formed'U-sliaped incross section, isspaced concentrically from the upper edge portion of the wall of 1 theinner vessel and is provided with an outwardly and upwardly inclineddeflecting flange l9; whic his' maintained in direct physicalcontactwith theinner surface of the wall-of the H inner vessel. I, ff

.A distributorplatefll is supported within theg 5 Wall 8aand this plateisforme'd with innumerable spaced apartair openings 2! and may be Theunderside of this'fplateis"formed with a series of 'radiatingtracks' 23,which are designed to 9 conduct small air bubbles from the small-airopenings 81) of the member 8 to the central air opening 22, across anyof the small openings2l, which intersect the bubble channels, or groovedtracks. 7

The air stream is forced under this distributor plate by the'action ofthe motor driven fan, and

is divided into small jet streams. The air flows air through the water.In causing the air to pass through the water or in frictional contactwith it, it is advisable that the air be broken up into minute masses,so that there will be the maximum frictional contact between the water 5and the air masses.

This useful result is accomplished by causing the air to be dischargedthrough small openings around the distributor plate, and then causingthe air to break up into small bubble masses,

by its movementthrough the water, or against the water, in groovedtracks or channels, so that the individual bubbles in one grooved trackor channel will be prevented from combining With any adjacent bubbles,with the result that the contained air will have less frictional contactwith the water.

The under surface of the distributor plate is preferably roughened, sothat it will be effective in breaking up the air bubbles, and causes.discharge of the released air through the intermediate air openings 2|formed in the distributor plate.

' The deflecting flange or baiiie ring i9 reduces the area of the airpassage adjacent the air openings 8b, so that pressure is slightlyincreased, resulting in a more forcible movement 01' the air through oragainst the water. Y The breaking up of the air bubbles may be also Eaided by providing an intermediate channel or track 24, across thegrooved tracks or channels 23, and the bubbles flowing along the tracks23 will strike against the sharp edges of the broken sides or walls ofthe adjacent or inner sections of the tracksia, in crossing theintermediate roove 24. V

.In Fig. 6 I show a helical arrangement of grooved bubble tracks 25, theouter ends of which are located at the marginal edges of the distributorplate 26, and the inner ends of which are located, near the center ofthe plate, which may be provided with 'a central discharge openin: 21.Small air openings 28 are formed in the plate 26 to allow air bubblesto, discharge mat any point along the grooved tracks. The bottom surfaceof this plate may be formedwith small projections adapted to pierce thebubbles, so as to release the airthrough the openings 28. Y

The air from the room is clrculatedthrough thefspace between the innerand outer vessels. by the forcing pressure of the motorized fan. Thewall of the inner vessel is maintained at a low temperature by means ofa cooling medium, -=such as ice or any chemical or mechanical re- 50frigeration means. As the flowing stream of air passes over the chilledsurface of the inner vessel moisture contained in the air stream willcondense and accumulate at the bottom of the t outer vessel, from whichit maybe withdrawn by means of the drain cock 29. A gauge level glass 30is provided for indicating to the operator the present level of thewater. By removing the member 8 additional water may be supplied to theinner vessel, or it may be poured directly over the distributor plate.

The inner tank may be formed with corrugations 32, intended to increasethe surface area of all vertical surfaces thereof, to accelerate thecooling of the air flowing against the outer surface, while increasingthe area of the surface exposed to the ice water.

A small upstanding cone 3! is supported directly under the centralopening 22, and its smaller end is located in spaced relation to theopening 22. This cone tends to prevent the ice from wedging in theopening, as it melts, and thus tends to promote uniform melting of theice.

The air passing against the wall of the inner vessel is not only cooled,but is to some extent dehydrated. At it flows in frictional contactthrough or against the water it gives up particles of dust, and isthereby purified. The operation of the apparatus, therefore, results inthe cooling, dehydration and cleaning of the air.

The parts of the device are entirely self contained in a portable unit,which may be moved from place to place, without aifecting the operation.

Having described my invention I claim:-

1. An air conditioning portable device consisting of a vessel, a tankwithin the vessel and spaced apart therefrom to provide an air passagebetween itself and the vessel, means for forcing air through the airpassage, means for maintaining the tank chilled, a distributor platelocated above the tank and provided with air openings and with bubbledirecting grooves crossing said air openings, and means for causing theair leaving said air passage to flow through the grooves.

2. An air conditioning device consisting of a tank adapted to contain acooling medium and provided with an exterior cooling surface, anenclosure for saidtank providing an annular passage against said coolingsurface, means for inducing a strong air movement upwardly through saidpassage, an annular deflector supported by the second tank and extendingover the upper edge of the first tank and provided with dischargeopenings through which the air may flow, and a distributor bladesupported centrally of said deflector and provided with perforations topermit the air to escape vertically and with a series of bubble formingribs on its lower surface adapted to be immersed in a cooling liquidarranged in the first tank.
